  org.eclipse.jgit.lib.IndexDiff

public class IndexDiff
extends Object

Compares the index, a tree, and the working directory Ignored files are not taken into account. The following information is retrieved:

• added files
• changed files
• removed files
• missing files
• modified files
• conflicting files
• untracked files
• files with assume-unchanged flag

Constructor Detail

IndexDiff

public IndexDiff(Repository repository,
                 String revstr,
                 WorkingTreeIterator workingTreeIterator)
          throws IOException

Construct an IndexDiff

Parameters:

repository -

revstr - symbolic name e.g. HEAD An EmptyTreeIterator is used if revstr cannot be resolved.

workingTreeIterator - iterator for working directory

Throws:

IOException

IndexDiff

public IndexDiff(Repository repository,
                 ObjectId objectId,
                 WorkingTreeIterator workingTreeIterator)
          throws IOException

Construct an Indexdiff

Parameters:

repository -

objectId - tree id. If null, an EmptyTreeIterator is used.

workingTreeIterator - iterator for working directory

Throws:

IOException

Method Detail

setFilter

public void setFilter(TreeFilter filter)

Sets a filter. Can be used e.g. for restricting the tree walk to a set of files.

Parameters:

filter -

diff

public boolean diff()
             throws IOException

Run the diff operation. Until this is called, all lists will be empty. Use diff(ProgressMonitor, int, int, String) if a progress monitor is required.

Returns:

if anything is different between index, tree, and workdir

Throws:

IOException

diff

public boolean diff(ProgressMonitor monitor,
                    int estWorkTreeSize,
                    int estIndexSize,
                    String title)
             throws IOException

Run the diff operation. Until this is called, all lists will be empty.

The operation may be aborted by the progress monitor. In that event it will report what was found before the cancel operation was detected. Callers should ignore the result if monitor.isCancelled() is true. If a progress monitor is not needed, callers should use diff() instead. Progress reporting is crude and approximate and only intended for informing the user.

Parameters:

monitor - for reporting progress, may be null

estWorkTreeSize - number or estimated files in the working tree

estIndexSize - number of estimated entries in the cache

title -

Returns:

if anything is different between index, tree, and workdir

Throws:

IOException

getAdded

public Set<String> getAdded()

Returns:

list of files added to the index, not in the tree

getChanged

public Set<String> getChanged()

Returns:

list of files changed from tree to index

getRemoved

public Set<String> getRemoved()

Returns:

list of files removed from index, but in tree

getMissing

public Set<String> getMissing()

Returns:

list of files in index, but not filesystem

getModified

public Set<String> getModified()

Returns:

list of files modified on disk relative to the index

getUntracked

public Set<String> getUntracked()

Returns:

list of files that are not ignored, and not in the index.

getConflicting

public Set<String> getConflicting()

Returns:

list of files that are in conflict

getIgnoredNotInIndex

public Set<String> getIgnoredNotInIndex()

The method returns the list of ignored files and folders. Only the root folder of an ignored folder hierarchy is reported. If a/b/c is listed in the .gitignore then you should not expect a/b/c/d/e/f to be reported here. Only a/b/c will be reported. Furthermore only ignored files / folders are returned that are NOT in the index.

Returns:

list of files / folders that are ignored

getAssumeUnchanged

public Set<String> getAssumeUnchanged()

Returns:

list of files with the flag assume-unchanged

getUntrackedFolders

public Set<String> getUntrackedFolders()

Returns:

list of folders containing only untracked files/folders

getIndexMode

public FileMode getIndexMode(String path)

Get the file mode of the given path in the index

Parameters:

path -

Returns:

file mode
